The connecting part between the mission module and the bus module has low thermal conductivity to reduce heat penetration to the telescope module and low vibration transmissibility to reduce the micro-vibration transferred to the telescope module. As the stiffness of the connecting part is quite low, some kind of damping mechanism are demanded to suppress natural frequency of the connecting part, but dampers utilizes viscoelastic material or oil are not applicable as the operating temperature of the connecting part is supposed to be around 30 K. In this paper, we studied applicability of eddy current damper for the connecting part of SPICA., 資料番号: AC1500025000, レポート番号: JSASS-2014-4143}, publisher = {日本航空宇宙学会(JSASS), The Japan Society for Aeronautical and Space Sciences (JSASS)}, title = {極低温用渦電流ダンパ}, year = {2014} }
